/* ============================================================================
   Tool pages
   ----------------------------------------------------------------------------
   Loaded after css/app.css, which owns the palette, the theme switching and the
   shared chrome (topbar, buttons, panels, byline). Nothing here redefines a
   colour: every value below is one of the tokens on :root, so the tool pages
   follow light and dark exactly as the calculator does.

   What this file adds is the two things the tool pages have and the PI-RADS
   page does not: the question/result split, and a long prose column under it.
